My favourite singer?

Demetria Devonne Lovato or Demi Lovato was born the 20th of August on 1992 and she is an American singer, actress and songwriter. Right now she is 24 years old.
She is my favourite singer since I was little because she was acting in a lot of films and series and I have seen them almost all. I really like how she act but I like more shen she sings, she do that with a potential voice
One of the films is Camp Rock and Camp Rock 2, the most known, another film is Princess Protection Program, Sonny with a chance (Sunny entre estrellas in Spanish) that it was the best serie for me in this year, she also did some chapters of Grey's Anatomy and some of the serie Glee. I think she did more series but they couldn't do de Spanish version.
She has changed her appearance a lot but she still have the same attitude and that's what I like of her too.
I'm not a big fan of her, but if I would have to choose any famous or any singer, I would choose her.
